Find LCM of 252,989,942,540 with Prime Factorization
| 2 | 252, 989, 942, 540 |
| 2 | 126, 989, 471, 270 |
| 3 | 63, 989, 471, 135 |
| 3 | 21, 989, 157, 45 |
| 7, 989, 157, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 989 x 157 x 15 = 586931940
Therefore, the lowest common multiple of 252,989,942,540 is 586931940.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
252 x 989 x 942 x 540 = 126777299040
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
989 : 1, 23, 43, 989
942 : 1, 2, 3, 6, 157, 314, 471, 942
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 252,989,942,540, is 1.
Now, the common factors can be found like this.
252:2x 2x 3x 3x 7
989:23x 43
942:2x 3x 157
540:2x 2x 3x 3x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 3x 3 = 216
Therefore, the value for common factors is 216.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 126777299040/(1x216)
LCM = 126777299040/216
LCM = 586931940
Thus, we can understand that the LCM of 252,989,942,540 is 586931940.
